After this, one more patch tuesday for Win10 and that's it. Unless user opt in for the extension.

I'm slowly migrating my machines from 10 to 11. Trying to hold on to W10 for as long as I can.
Now I'm starting to feel W11 is also good after a few tweaking and optimizations.

I have not tried it thou. I believe you need to update to the latest Win10 build and opt in for the windows backup. Or do a clean install via media creation tool and opt in for backup?

Let me know how you did it so I can apply it.
